IPC: H01J49/02
Filed: 1990-02-21
Abstract: PURPOSE: To measure a magnetic field at a less count step and significantly increase a measuring speed thereof by simultaneously detecting a range of a limited ion mass by a double focus mass spectrometer having an electro-optic ion detector. CONSTITUTION: A fused fiber optical window 134a is pulled in a bundle 134b with its rectangular section and fused, and the bundle 134 is heated and formed into a fused glass ribbon 134c and cut with a specified length L. A width of the ribbon is equal to a length of a desired focus face, a thickness is enough thin in which an output side image can depend upon the thickness of an image plate and a photo-diode detector array 140. Thus, the fiber is fused in the ribbon shape, cooled, twisted by 90 degrees, and bent so that a twisted part 152 is exceeded to form a part 154. Then, a fiber terminal obtains maximum light ray reception efficiency. Consequently, double focus mass spectrometer having an electro-optic ion detector is formed, and a range of a limited ion mass is detected simultaneously, thus making it possible to measure a magnetic field at less count step.

Title: Ink supply apparatus in ink jet printer
Inventor: SHIODA TOYOJI
IPC: B41J2/175
Filed: 1983-03-09
Abstract: PURPOSE:To make it possible to reduce running cost, by constituting the titled apparatus so that the constitution of an ink storage container is formed of only an outer shell while an ink pressurizing means and an ink residual amount detecting means are placed out of the ink storage container. CONSTITUTION:When an ink storage container 301 is inserted into a container receiver 304, a pipe needle 305 pierces a plug 303 to inject ink to a second ink storage container 307 hermetically closed by an elastic membrane 308 and supplies the same to an ink sump 105 through a filter 310 and a supply line 106. In mixing air bubbles in the nozzle of a recording head, when an air vent orifice 302 is closed by a finger and the container 301 is forcibly pushed down, the ink pressures in both containers are raised by the deformation of the elastic membrane 308 and air bubbles are expelled from the nozzle while adered dust is washed off. If addition, an ink liquid level detecting part 312 is provided to the second ink storage container 307. By this mechanism, the ink in the ink storage container can be used without wastefully leaving the same and running cost can be reduced.

Title: Charge transfer device
Inventor: MURAYAMA KOUJI
IPC: G11C27/04
Filed: 1980-03-26
Abstract: PURPOSE:To enable signal transmission less in distortion over a wide voltage range, by gradually decreasing the storage capacitance along the charge transfer direction. CONSTITUTION:To the storage capacitance Ci at input side, the storage capacity of each transfer stage is reduced gradually by a fraction of transfer efficiency A. Since the setting is made like this, the remaining charge at each tranfer stage is absent and the voltage Vin across the capacitance Ci can be transferred as it is without being attenuated. Thus, the input/output characteristics are completely linear in the range smaller than the input voltage of VC-VT, and the voltage of small amplitude can be transferred. Thus, the signal transmission with less distortion over a wide voltage range can be made.

IPC: G01N25/02
Filed: 1994-03-09
Abstract: PURPOSE:To improve the adhesiveness of the image of a sheet to be inspected to an identifying sheet and identifiability by consisting of a pressurizing member of an elastic material and forming the pressurized contact surface with the sheet to be inspected of scattered small projecting surface groups. CONSTITUTION:The pressurizing member consists of the pressure contact part 10-2 to be brought into pressurized contact with the identifying sheet by direct contact therewith and a push button part separate from the pressure contact part. The push button part is formed by properly working members having rigidity, synthetic resin, etc. Elastic materials, for example, rubber, etc., are selectable for the pressurized contact part 10-2. The pressurized contact part 10-2 is formed to a collared columnar shape as well and the pressurized contact surfaces 10-2a are composed of the many small projection surface groups. As a result, the pressure per unit area on the respective pressurized contact surfaces 10-2a is increased and the pressurized contact surfaces are distributed and, therefore, the conditions for adhesion of toners are improved and the check is facilitated as well. The pressurized contact surfaces 10-2a consisting of such small projection groups are smaller than the identifying sheet and since the identifying sheet is partially brought into pressurized contact with the sheet to be inspected and, therefore, the peeling operation for the purpose of checking the adhesion of the toners is easy after pressurizing and heating.
